CAST-WHEEL CONSTRUCTION.

Application filed February 2, 1925. Serial No. 6,378. i

To all whom it may concern. respectively, of the hub section 1 comprises Be it known that I, ELMER F. WATERnon, the converging arcuate wall sections 8 and 9, a citizen of the United States of America, which at their front edges connect into-each residing at Detroit, in the county of Wayne other and at their rear edges connect into the 5 and State of Michigan, have invented ceropposite edges of the rear wall 4. The front tain new and useful Improvements in Cast wall 5 at its point of mergence with the \Vheel Construction, of which the following front and peripheral walls of the hub secis a specification, reference being had therein tioh comprises the conver ing arcuate wall to the accompanying drawings. sections 8 and 9 and the intermediate wall 10 The invention relates to cast wheel 0011- section 10 therebetween, this intermediate structions and refers more particularly to wall section being substantially parallel to cast malleable iron wheels, which are parthe rear wall 4.

ticularly applicable to motor Vehicles, One With this construction of spoke wherein of the objects of the invention is the prothe peripheral width thereof is greatest advision of a cast wheel having spokes with a jacent to the rear Wall, I am enabled to cast cross sectional contour, such that the parting the wheel so that the parting line does not 05 line of the mould will not show from the show on the front surface. Also moulding front of the wheel. Another object is to so is sin'iplified inasmuch as the largest portion constructthe spokes that the moulding of of each spoke, which forms the front surthe wheel will be simplified and at the same face thereof, is in the drag of the mould so time the front surfaces of the spokes will be that I am enabled to use a shallow mould 70 smooth. A further object is to provide a cope and at the same,v time the front surface wheel of sturdy appearance and of great will be smoother than if located'in the mould strength. cope. Furthermore, the design is such that IVith this as well as otherobjects inview a wheel is provided having a sturdy appearthe invention resides in the novel features ance and great strength. "(5 of construction and combinations and ar What I claim as my invention is: rangements of parts as more fully herein 1. A cast metal wheel including a hub afterset forth: section and spokes integral therewith and In the drawings: merging thereinto, said spokes at their Figure l is a side elevation of a portion points of mergence into said hub section havof a cast metal wheel embodying my invening substantially parallel portions and art-ution. ate portions merging into said parallel por- Figures 2, 3 and 4 are cross sections retions. spectively on the lines 2-2, 3-3 and 4-4 2. A cast metal wheel including a hub of Figure 1. section and spokes integral therewith and The cast metal wheel is preferably formed merging thereinto, said spokes at their of malleable iron and comprises, the hub points of mergence .into said hub section section 1, the telly section 2 and the spoke having substantially parallel portions and 40 3 integral with and connecting the hub and areuate portions merging into said parallel felly sections. Each spoke is hollow portions and said spokes beyond their points throughout its length and also is of a general of mergence into said hub section hav'ing a half round cross sectional contour, which portion corresponding to one of said sul progressively decreases in.area radially outstantially parallel portions. and converging: 45 ward from the hub section. The rear wall portions merging into said last mentioned l of each spoke is substantially flat while the portion and into each other. or.

front wall 5 is substantially half round. In testimony whereofI affix my signature. This front wall beyond its point of mergence with the frontand peripheral Walls 6 and 7 ELMER F. WATERBOR.-
